what is the function of "__barebox_early_initcalls_end"?

[Robert P. J. Day]

  while perusing common/startup.c, i noticed:

extern initcall_t __barebox_initcalls_start[], __barebox_early_initcalls_end[],
                  __barebox_initcalls_end[];

but i don't see any other reference to that "early" initcall variable,
and it doesn't show up in System.map.

  what is it used for?  thanks.
